While some rays have stayed within the limits of the cave systems where they first evolved, others are relatively more recent adaptations to new environments, likely the results of overpopulation.Īll of the rays on 4546B have given up predation in favor of herbivorous scavenging, and use poisonous flesh to protect themselves. A fast and fearsome stalker of small creatures in the dark. It would have most resembled the ghostray in size and appearance, with translucent skin for camouflage and forward-mounted eyes for hunting. The 'alpha ray' would have evolved deep in the ocean trenches, quickly growing in line with available food supplies.
Ghostrays, jellyrays, crimson rays and rabbit rays likely all share a common evolutionary ancestor. The specimens are 99.99% genetically identical to those encountered on the planet today, suggesting that rays in particular have undergone little evolutionary mutation in the past millenium. Different species of ray indigenous to 4546B, each adapted to different environments.
